SNAP-FASTENER.

Application filed February 26. 1917. Serial No.

To (ZZZ whom it may concern Be it known that I, INGEMAR ANnnnsoN,

a subject of the King of Sweden, and resident of Ridgefield Park, State of New Jersey, have made a certain new and useful Invention in Snap-Fasteners, of which the following is a specification.

his invention relates to snap fasteners and has for its object to provide an improved spring sna ple in structure, e exceedingly cheap I ther object of the invention is to provide a snap fastener of this character which is not liable to injury from mangling or ironing in the usual laundry operations.

Further objects of the invention will appear more fully hereinafter. The invention consists substantially in the construction, combination, location and'relative arrangement of parts, all as will be more fully hereinafter set forth as shown in the accompanying drawing and finally pointed out in the appendant claims.

Referring to the draWin Figure 1 is a top plan view of an assembled spring fastener, embodying my invention. Fig. 2 is a sectional view of the same taken on the line 22, Fig. 1 and looking in the direction of the arrows. Fig. 3 is a top plan view of the female section of the snap fastener. Fig. 4c is a. similar view of the male section of the snap fastener.

The same part is desi reference numerals w erever throughout the several views.

It is the purpose of my invention to provide a snap fastener which is exceedingly cheap of manufacture, the respective sections of which may be made with but a single stamping and to the female section of which amount of resiliency is imparted, due to the particular form of the same, thereby providin an exceptionally eiiicient clasp which efi ectually retains the male section secured thereto, but at the same time allows the male section to be withdrawn from engagement therewith without the danger of springing the engagin portions of the female section and there y diminishing its retaining power.

In the drawing I show the female section at 1 and the male section at 2. The female section comprises a ring which has stamped out of the same a plurality of circumferentially extending slots 3, the intervening porcient in operation, and in-manufacture. A furit occurs Specification of Letters Patent:

tions of the body of the section at 4 bein of. In e 1 indicated depressed by the stamping therering 1 with a of the exact center of the section, and comparatively small radially extending slots 8, one for each circumferentially extended slot the central hole 7 and said slots 3.

With this structure it will be seen that I provide a female section in which is secured great resiliency and wherein the liability of n ury from any cause is reduced to a minimum. The circumferentially threads for securing this section to thegarment may pass through these slots without in any way interfering with the operation of the spring securing portions thereof. The male section 2 is of the usual structure and comprises the flat portion provided With-a plurality of openings 9 to accommodate the threads for securing the same to the garment and a central located head 10 of larger diameter than the central opening 7 of the fe- V The operation of the device is resiliency of the spring portion 6 of the fastener allows the head 10 of the male portion 2 to be inserted through the hole 7 and also effectually serves to retain the male section inserted therein.

aving now set'forth the object and na ture of my invention and having shown and described a specific structure embodying the principles, what I-claim as new and useful, and all my own invention, and desire to secure by Letters Patent is;

1. A snap fastener comprising a flat ring provided with circumferentially extending slots and spring elements, said spring elements being depressed circumferentially below the plane of the body of said flat ring at the portion thereof in which said circumferential slots are located, and provided with a central opening therethrough and radially extended slots extending from said central opening to said circumferentially extended slots, and a complementary piece provided with a projection thereon of larger diameter than said central opening, adapted to be inserted therethrough.

2. A snap fastener comprising a fiat ring provided with circiunferentially extending slots and springelements, said spring elements being circnniiferentially depressed at one portion thereof below the plane of the body of said fiat ring, and provided with a central opening therethrough and radially extended slots extending from said central opening to said circumferentially extended slots, and a complementary piece provided with a projection thereon of larger diameter than said central opening, adapted to be inserted therethrough, and perforations in said complementary piece for the reception of stitches.

3. The combination with a flat ring provided with circnmferentially extending slots and a central opening, and comparatively narrow radially extending slots, extendin between said central opening to each of sai circnmferentially extending slots and the portion of said flat ring between said circumferentialiy extending slots being depressed below the plane of said fiat ring substantiaily as and for the purpose described.
